Happy #UNDay! 💙 The IAEA is proud to be part of the @UN family and support countries around the globe through nuclear science — from expanding cancer care through #RaysOfHope, boosting food security with #Atoms4Food to improving water management and ensuring nuclear safety.

Happy #UNday to all who celebrate! I've seen up close how 🇺🇳 agencies like the @iaeaorg, @UNODC, & @UNOOSA keep the 🌎 safer, more healthy, more secure, more stable thru cooperation on tech, governance, development, energy & more -- improving 🇺🇲 safety, security, & prosperity.

Thrilled to work with the Center on Global Energy Policy Announces as a Distinguished Visiting Fellow on safely and securely deploying advanced #nuclear ⚛️ energy!

Great film, important questions. Looking forward to joining this panel discussion @penn_state!

Loved moderating this @INMMTweets panel on nuclear safeguards & security by design, feat. reps from @TerraPower & @WECNuclear. Great to hear how "baking in" security & safeguards during design expands market access & simplifies reactor ops. Want more? 👉🏻 NuclearNexus@nnsa.doe.gov

The US is taking ambitious steps to advance civil nuclear with leadership on nuclear–AI nexus. We’ll continue our cooperation on this & other areas. Exchanged with @ENERGY’s @SecretaryWright on this and situations in Iran & Ukraine. Thanks to 🇺🇸 for its key support to @IAEAorg.

INMM President Tina Hernandez and NGFP Program Manager Tom Gray signed a partnership agreement at INMM 2025 in Washington DC aimed at inspiring and equipping students to pursue rewarding careers in national security and global safety domains.

Hey #INMMTweets! Were you inspired by @rafaelmgrossi's words? Stop by the @BrookhavenLab's booth to learn more about its support to @iaeaorg's #safeguards technology needs 👉🏻 https://t.co/YaGe1rXnWM & how it helps 🇺🇲 applicants for IAEA jobs! 👉🏻

The IAEA is committed to empowering women to thrive in nuclear-related fields, and Kirsi Alm-Lytz is a shining example. As Head of the Regulatory Activities Section, she’s helping countries strengthen their nuclear safety frameworks. Read her story → https://t.co/vnHc9frniJ

80 years ago this week, Hiroshima and Nagasaki were destroyed by nuclear weapons. Make nuclear weapons history. @NTI_WMD

...move now to REDUCE risks, REDUCE weapons, REDUCE uncertainty through diplomacy and cooperation so we can INCREASE human security, and thereby honor those lives tragically lost 80 years ago and ever since through the dangerous and futile pursuit of nuclear superiority.

#Nuclear risks have changed much since the 🇺🇲 used the first #nuclearweapon 80 years ago, and we may be in even graver danger today, with conflict and rhetoric rising in regions with nuclear-armed adversaries. Leaders & publics must recall the horrors of #Hiroshima and...

Since Trump took office, Virginia’s economy has taken a hit — and the Youngkin-Sears Administration has stayed silent on the very policies hurting our businesses. As Governor, my administration will take action to invest in and grow Virginia’s economy. And unlike my opponent,

400+ artists from around the world took the challenge to re-imagine nuclear energy in pop culture. The winning works, showcased at #LetsTalkNuclear with @Gen_Atomic, @sci_Phile, @Princymthombeni, explored how art can change the narrative around nuclear energy.

The recent evacuation at Fukushima is a stark reminder that nuclear facilities must be built and maintained with resilience at their core. As climate-driven disasters grow in frequency and intensity, nuclear material security is increasingly important. https://t.co/G752IC7R4b

Great piece by @ThirdWayEnergy on recent #nuclearenergy #EOs. Americans agree: we need more safe, secure, reliable⚛️energy. Countries around the 🌍want 🇺🇸 ⚛️ tech. These EOs risk strangling the🔑to that demand: a competent, efficient, independent @NRCgov.

trump, Stephen Miller, and Tom Homan are FURIOUS about this ICEBlock app, which informs folks where ICE is operating. So you definitely shouldn't RT this like crazy, because it would make trump even madder.

Important thread pointing out the nuanced reality we're dealing with right now. No one knows for sure whether/how/when #Iran could/would halt/reconstitute/sprint their #nuclear program, including Iran. Thank you, @NicoleGrajewski, for your ongoing insights.

We are hiring! Check all positions that are closing soon and apply before the deadline: https://t.co/hWWqRUX2dO #UNjobs #IAEAjobs

A big milestone: @IAEAorg and @WorldBank are joining forces to bring nuclear to more countries. https://t.co/CgiGsowmSs
